 the strip grooves on the metal cover plate are used for radiating a signal of antennas corresponding to the strip grooves, or transmitting electromagnetic waves outside the electronic device to the antennas corresponding to the strip grooves through the strip grooves. 
 
     
     
       7. The device according to  claim 1 , wherein:
 the U-shaped grooves separate the plurality of side surfaces of the metal frame into metal pieces of the metal frame, and the metal pieces are used as radiators of antennas supporting the fifth generation mobile communication network. 
 
     
     
       8. The device according to  claim 7 , wherein:
 the metal pieces are not grounded, and the metal pieces are provided with feeding points, and the feeding points are connected to antenna feeding networks coupled to the electronic device to support the fifth generation mobile communication network. 
 
     
     
       9. The device according to  claim 8 , further comprising:
 a printed circuit board carrying the antenna feeding networks; 
 wherein the printed circuit board is disposed on one or more side surfaces of the plurality of side surfaces of the metal frame each having one or more of the U-shaped grooves. 
 
     
     
       10. The device according to  claim 1 , wherein:
 the plurality of side surfaces of the metal frame include two first side surfaces and two second side surfaces, the first side surfaces are perpendicular to the second side surfaces, and a length of each of the second side surfaces is longer than a length of each of the first side surfaces; and 
 the U-shaped grooves are disposed on the second side surfaces of the metal frame. 
 
     
     
       11. The device according to  claim 10 , wherein:
 each of the second side surfaces is provided with two of the U-shaped grooves that are respectively located at two ends of the second side surface. 
 
     
     
       12. The device according to  claim 1 , wherein the U-shaped grooves divide the metal frame into a metal frame body and metal pieces. 
     
     
       13. The device according to  claim 12 , wherein all sides of each of the metal pieces are spaced apart from the metal frame body.
